ios - 检测 MKMapView 何时停止移动
<p><p>每当用户移动我的 MKMapView 时，我都会在 map 上加载更多图钉。现在，我正在使用这段代码来检测他们何时拖动它:</p>
<pre><code>- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer {
return YES;
}
- (void)didDragMap:(UIGestureRecognizer*)gestureRecognizer {
if (gestureRecognizer.state == UIGestureRecognizerStateEnded){
CLLocationCoordinate2D topLeft, bottomRight;
topLeft = ;
CGPoint pointBottomRight = CGPointMake(self.mapView.frame.size.width, self.mapView.frame.size.height);
bottomRight = ;
;
}
}
</code></pre>
<p>但是，这只检测用户何时停止拖动。用户可以“ throw ” map ，并且在他们完成“拖动”后 map 仍然可以移动。有什么方法可以找到 map 停止移动的时间吗？谢谢</p></p>
